Hello,

we've just noticed a quite serious regression in debug info output
in GCC 4.0 over previous releases: when building with -funit-at-a-time
(which is on by default with -O2), *no* debug info for global variables
appears to be emitted at all.

I could not reproduce it with any of the following examples on 
i686-pc-linux-gnu
with dwarf-2:
static int i;

int main(void)
{
  i += 3;
  i *= 5;
  return 0;
}

int i;

  i += 3;
  i *= 5;
  return 0;

Do you have an example which fails?

Thanks,
